This is a homemade fermentation machine from the Homemade Association. - Temperature display: Yes - Number of shelves: 3 - Includes a water tray Thank you for viewing. I purchased this when I was attending a class and used it a few times, but I haven't had the opportunity to use it since then, so I've kept it carefully stored. I have re-checked the operation for this listing. There are no problems with the functionality. Since it was originally for fermentation, there is no noticeable dirt and it is in a clean condition. I think you will be able to use it comfortably. Please check the model number in the photos. Accessories include 3 wire shelves and a water tray. I am working, so packing and shipping will be on weekends, please understand.
